It a good motor for the money. I put a 11t pinion gear in it and it crawls and it hauls. I will buy Holmes Hobbies motors again.

Awesome for a TRX-4 Sport... I put this in my TRX-4 Sport kit when I built it and man does it have a lot of power. Paried with a 1080 esc on 3s its good for trails and crawling. I would definitely recommend

Bought this to put in my SMT-10 and I couldn't be happier. 15 tooth pinion, 56 spur. Truck has lots of low end grunt and good top end. I highly recommend HH motors 5 slot is great.
